No. The orientation tag is taken into account when the image is loaded 
into memory.

The resize happens on the image in memory.

It is then saved, overwriting the old file. The image is already 
oriented in the standard way.

To save it with your original orientation tag, another step would be 
required to rotate the image and copy the original tag. There is no 
advantage to adding that degree of complexity (and slowness).

The resulting image should look correct, of course. If it doesn't, there 
is a bug. But the orientation tag should be reset.
